The first plug 12 is rotated in a damping manner during the rotation, or has stop points in both the first receiving position and the first plugging position such that the first plug 12 does not shake without an external force.

A circuit board and other electronic elements connected to the circuit board are provided in the housing 11, and in order to achieve the connection between the power adapter and other electronic devices or connecting wires, the power adapter further comprises a plurality of interface seats for plugging in external connectors, and the interface seats are electrically connected to the circuit board; referring to FIG. 3, the housing 11 is provided with interface holes 103 corresponding to the interface seats. The connectors of the external electronic devices or connecting wires can be in plugging fit with the interface seats through the interface holes 103 to enable electrical connection between the power adapter and the external electronic devices or connecting wires. The number and type of interface seats may be set according to requirements, and in the embodiment of the present application, the interface seat may be one of a USB-Type-C interface seat, a USB-Type-B interface seat, a TF card interface seat, an audio interface seat and an HDMI interface seat to meet the requirements of different plugs.

Referring to FIGS. 1 and 2, the adapter mechanism 20 comprises a plug seat 21, a second plug 22 and a second plugging structure 23 pluggable into the first plugging structure 13, wherein the plug seat 21 has a third mounting surface 211 and an attachment surface 212 that face away from each other, and the first mounting surface 101 and the attachment surface 212 may be substantially parallel to each other.

Preferably, the second plugging structure 23 can be plugged into the first plugging structure 13 and into the first plug 12 when the first plug 12 is in the first receiving position, so as to prevent the first plug 12 from taking up space, and also to play a protective role on the first plug 12.

Referring to FIG. 2, in the illustrated embodiment, the first mounting surface 101 is an end surface having a small area, and the second mounting surface 102 is relatively long. When a plug jack direction of the socket is a horizontal direction, namely, the socket is taken on a vertical surface, if the power supply body is plugged into the socket by means of the first plug 12, the weight of the housing 11 itself is applied to the first plug 12, causing the first plug 12 to be detached from a plug jack of the socket; if the adapter mechanism 20 is mounted on the power supply body, the power adapter can be plugged into the socket with the plug jack facing the horizontal direction in this case so as to prevent the power adapter from being detached from the socket due to its own weight.

The adapter mechanism 20 of the power adapter can achieve the connection with the power supply body by means of the plugging fit between the first plugging structure 13 and the second plugging structure 23, in this case, the second plug 22 is electrically connected to the first plug 12, and the power adapter is switched from plugging into the external socket by means of the first plug 12 to plugging into the external socket by means of the second plug 22; a plugging direction of the first plug 12 faces away from the first mounting surface 101, a plugging direction of the second plug 22 faces away from the third mounting surface 211, the attachment surface 212 facing away from the third mounting surface 211 is attached to the second mounting surface 102, the first mounting surface 101 and the second mounting surface 102 are provided at an included angle, and therefore, the plugging direction of the second plug 22 and the plugging direction of the first plug 12 are provided at an included angle, so that a plugging direction of the power supply body 10 is changed by mounting the adapter mechanisms 20 without replacing the power adapter again; when the power adapter is plugged into the external socket, whether to mount the adapter mechanism 20 may be selected according to the requirements for the plugging direction and space; and the power adapter has good applicability and is convenient for a user to carry.

Referring to FIG. 2, in this embodiment, the first plugging structure 13 comprises an accommodating slot formed in the first mounting surface 101 and penetrating to the second mounting surface 102, and the second plugging structure 23 comprises a plugging block. When the first plug 12 is in the first receiving position, the first plug 12 is accommodated in the accommodating slot, and the plugging block can be plugged with the accommodating slot and the first plug 12, and the first plug 12 plays a limiting role on the plugging block, preventing the plugging block from dropping from an opening of the accommodating slot. In this way, plugging of the first plugging structure 13 and the second plugging structure 23 is achieved. The accommodating slot is used for accommodating the first plug 12 to save space. The plugging block protrudes from the attachment surface 212. In other embodiments, the first plugging structure 13 may also be a plugging block, and the second plugging structure 23 may also be an accommodating slot.

The first plug 12 may be a two-phase or three-phase plug, and when the first plug 12 is the two-phase plug, the first plug 12 comprises two first pins, and the two first pins may be corotated and parallel to each other. Correspondingly, two accommodating slots are provided and the two accommodating slots are spaced apart from each other, a first pin is rotatably connected to a slot wall of one accommodating slot, and when the first plug 12 is in the first receiving position, two first pins are respectively received in the two accommodating slots.

Referring to FIG. 4, correspondingly, two plugging blocks are provided, and one plugging block is plugged with one accommodating slot and one first pin. The two plugging blocks are respectively plugged with two accommodating slots and two first pins, such that the connection between the adapter mechanism 20 and the adapter mechanism 20 is tighter and more stable, further preventing the shaking of the adapter mechanism 20.

Referring to FIG. 4, in order to achieve the plugging fit between the plugging blocks and the first pins, the end surface of the end of the plugging block away from the plug seat 21 is provided with a plugging slot 231, and when the first plug 12 is in the first receiving position and the plugging block is plugged into the accommodating slot, the first pin is plugged into the plugging slot 231 and is electrically connected to the second plug 22. An elastic piece 24 electrically connected to the second plug 22 is provided in the plug seat 21, and the elastic piece 24 extends into the plugging slot 231, and can elastically abut against the elastic piece 24 when the second plug 22 is plugged into the plugging slot 231, so as to electrically connect the first plug 12 and the second plug 22. The plugging slot 231 plays protective and limiting roles on the second pin 221, and the attachment surface 212 and the plugging slot 231 can jointly limit the separation of the plugging block from the second pin 221.

Referring to FIGS. 2 and 3, in order to facilitate the plugging fit between the plugging block and the accommodating slot, the accommodating slot is provided with a first sliding joint structure 14 on the slot wall thereof, the first sliding joint structure 14 extends in an extending direction of the accommodating slot, the plugging block is provided with a second sliding joint structure capable of being in sliding fit with the first sliding joint structure 14, and when the second sliding joint structure is slidingly connected on the first sliding joint structure 14, the plugging block is plugged into the accommodating slot. The first sliding joint structure 14 can limit the movement of the plugging block in a forming direction of the accommodating slot to improve the stability of connection.

Referring to FIGS. 2 and 4, in this embodiment, the first sliding joint structure 14 is a sliding slot formed in the slot wall of the accommodating slot, and the second sliding joint structure is a sliding joint block protruding from a side wall of the plugging block. The sliding slot plays guiding and limiting roles for the sliding joint block. The sliding joint block is elongated and extends in a forming direction of the plugging slot 231, and the sliding slot is formed in the slot wall of one accommodating slot close to the other accommodating slot. In other embodiments, the first sliding joint structure 14 may also be a sliding joint block protruding from the side wall of the plugging block, and the second sliding joint structure may also be a sliding slot formed in the slot wall of the accommodating slot.

Referring to FIGS. 2 and 3, in order to limit the separation of the adapter mechanism 20 from the power supply body, the adapter mechanism 20 further comprises a limiting plate 25 connected to the attachment surface 212, the limiting plate 25 protrudes from the attachment surface 212 and extends in the same direction as the plugging block, the second plugging structure 23 is connected to the limiting plate 25, and the limiting plate 25 can be attached to the first mounting surface 101 when the second plugging structure 23 is plugged into the first plugging structure 13. During mounting, the side surface of the limiting plate 25 facing the second plugging structure 23 is firstly attached to the first mounting surface 101, and the plug seat 21 is then pushed toward the second mounting surface 102 until the attachment face 212 is attached to the second mounting surface 102, and in this case, the second plugging structure 23 can be adaptively plugged into the first plugging structure 13, making assembly quick and convenient. The limiting plate 25 and the attachment surface 212 can jointly limit the shaking and displacement of the adapter mechanism 20 relative to the power supply body.

The clamping block protrudes from the first mounting surface 101, and when the second plugging structure 23 is plugged into the first plugging structure 13, the limiting plate 25 may tightly abut against the clamping block by means of slight elastic deformation, thus increasing a friction force between the limiting plate 25 and the power supply body.

Referring to FIG. 2, in order to achieve the clamping connection between the clamping block and the housing 11, the first mounting surface 101 is provided with a clamping slot 15, and when the second plugging structure 23 is plugged into the first plugging structure 13, the clamping block is clamped into the clamping slot 15. The clamping slot 15 plays positioning and limiting roles on the clamping block, and in the absence of an external force, the clamping fit between the clamping block and the clamping slot 15 limits the separation of the adapter mechanism 20 from the power supply body. When the adapter mechanism 20 is pushed by an external force, the limiting plate 25 causes the clamping block to slip out of the clamping slot 15 by means of slight elastic deformation, thereby separating the adapter mechanism 20 from the power supply body.

Referring to FIGS. 1 to 3, the plug seat 21 is preferably provided with a first plugging structure 13 on its third mounting surface 211. In this way, the plugging structure can be in plugging fit with a further external component having the second plugging structure 23 to achieve adapting. Specifically, the plug seat 21 is further provided with a clamping slot 15 for sliding joint with a further external component having the clamping block. The slot wall of the accommodating slot on the plug seat 21 is also provided with the first sliding joint structure 14 for sliding joint with a further external component having the second sliding joint structure.

In order to improve the applicability of the power adapter, the power adapter may comprise a plurality of adapter mechanisms 20. The second plugs 22 on the adapter mechanisms 20 may be plugs of different specifications, such as plugs conforming to the British, European, or American standards, which can be replaced or assembled as desired by a user. The adapter mechanisms 20 may further be plugged in sequence.

Based on the explanation herein, any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application, and other specific implementations of the present application conceived by those skilled in the art without involving any inventive effort should be included within the scope of protection of the present application.
